their distance from outer margin. Scutellum 1-32-1 -50 times as broad as long, hind margin 

 partly slightly elevated, interspaces narrow and apart from some interspersed tiny punctures, 

 smooth. Propodeum medially steep, convex (sometimes irregularly), median carina and plicae 

 distinct though not high. Upper mesepimerum more coarsely punctured than upper episternum, 

 interspaces narrow, smooth, both parts separated rather by colour than by a furrow. Hind 

 coxa very broad, dorsal edge with mesal carina not very conspicuous ; depression in upper part, 

 posteriorly including dorsal edge, smooth, anteriorly with sparse punctures, lower half moderately 

 punctured. Hind femur (Text-fig. 156) at base wide-angular, excluding teeth about 1-65 

 times as long as broad, teeth very long; puncturation in dorsal half near base rather coarse, 

 average interspaces about half as broad as punctures, smooth. In fore wing apical processus 

 of stigmal vein broader than but only one-third as long as uncus. 



Gaster slightly shorter than head plus thorax, relatively longer in darker bigger specimens: 

 in form A 1-49-1 -54 times, in B (small) 1-40-1-43 times, in C 1-63-1-73 times, as long as broad. 

 First tergite semiglobose, 1-3-1-5 times as broad as long, posteriorly with indicated median 

 smooth line, otherwise punctured, interspaces slightly narrower than punctures, smooth. 

 Fourth tergite medio-posteriorly distinctly produced, angulate (Text-fig. 154), here more than 

 half as long as first tergite, with fine median groove but without (broad) ovipositorial furrow. 

 Fifth tergite 1-15-1-33 times as broad as the first, strongly convex, basally subhorizontal, 

 posteriorly steeply declining, broad median furrow tapering and very shallow anteriorly; tergite 

 medially about twice as long as fourth tergite. Ovipositor sheaths reaching about middle of 

 fifth tergite. 



$. 4-8-5-0 mm (B), 6-5-7-4 mm (Q- Colour pattern similar to § of relevant form ($ of 

 form A not known). Gaster in dark form (C) black with one pair of pale latero-dorsal spots in 

 middle, ina^a vague spot on flat vertical part of carapace subapically; in form B first tergite 

 rufous with transverse yellowish macula, base of carapace dark, then mainly rufous-yellowish 

 in a vaguely interrupted arch and behind this two large submedian maculae on each side 

 separated by broader median black strip and, transversely, by narrow arcuate black lines. In 

 biggest specimen (from Ladismith, form C) sternites V and VI slightly longer than broad, in 

 the smallest (B) slightly transverse. 



The common features of this species are the long antennae and the long head. 

 Otherwise it seems easy to split the material at hand into three forms (A, B, C) 

 and it would be easy to name them. I doubt, however, whether this would be 

 wise, as all three forms come from a relatively small area. The closely related 

 L. tricolor Kirby shows how useless and confusing such naming might prove when 

 more material is known. 



Biology. Hosts unknown. The variation suggests that several host species, 

 possibly of Anthidiine bees, may be involved.
